2. The sounding software automatically detects the radiosonde and
begins the sounding preparations.
The sounding software goes through reconditioning and ground
check. The status is clearly indicated with a progress bar. During
the ground check, the following preparation steps are performed
for the radiosonde:
- T check: The radiosonde performs an in-built functional
temperature check.
- Reconditioning: Preparation of humidity sensor.
- Cooling after reconditioning
- U check: The radiosonde performs a physical zero humidity
check.
3. After the ground check is finished, the sounding software indicates
the results with a message. Remove the radiosonde from RI41.
Before the radiosonde is launched, you can return to the
preparation phase anytime by replacing the radiosonde on RI41.
The sounding software automatically returns to the ground check
phase.
If there is any delay in starting the sounding, for example, if you
must wait before launching the sounding balloon, you can switch
the radiosonde off by pressing the power switch. When you are
ready to launch the balloon, switch the radiosonde back on.
4. After radiosonde launch, proceed to monitor the sounding with the
sounding software.
